Kubernetes Operator Development with Go
After three days you build custom Kubernetes operators with Go. From Kubebuilder and Custom Resource Definitions through Reconciliation, Webhooks and Testing to production-ready deployment: all hands-on in your own cluster.
Workshop Details
What makes this workshop stand out
What you will learn and take away
After three days of operator training you independently develop Kubernetes operators with Go. Here is what you take away:
- Scaffold and implement your own operators: With Kubebuilder v4 and controller-runtime from empty project to working operator
- Secure and test operators: Admission Webhooks, CEL Validation, RBAC, and automated tests with envtest in a CI/CD-ready structure
- Deploy production-ready: Prometheus metrics, Leader Election, CRD versioning, and clean packaging with Kustomize
All exercises run in our cloud environment with a dedicated Kubernetes cluster. No local setup, no hassle. You take working operator code home with you.
Want to continue? Our Kubernetes Advanced Training deepens the cluster side where your operators run.
Why the investment pays off
Without operator know-how your team stays with manual processes or expensive commercial solutions for tasks that Kubernetes can automate natively. This training changes that:
- Automation instead of manual work: Your team can codify recurring cluster operations into Kubernetes operators, reducing error sources and response times
- Independence from third-party vendors: Instead of buying commercial operator solutions, your team builds custom operators tailored to your infrastructure
- Faster incident response: Operators with Prometheus metrics and automatic reconciliation detect and fix deviations before the on-call team has to intervene
Small groups of maximum 8 participants so we can address questions from your project context.
Prerequisites
Required:
- Solid Kubernetes knowledge: Pods, Deployments, Services, ConfigMaps, RBAC, and working with kubectl
- Experience with the Linux command line
- Basic understanding of container images and their build process
Not required:
- Go programming skills (the workshop starts with a Go crash course)
- Experience with operator development or Kubebuilder
- Knowledge of controller-runtime or client-go
Our Kubernetes Advanced Training provides the ideal preparation for the Kubernetes side.

Testimonials
How participants experience our trainings
Based on 1047+ participant reviewsacross all DevNinjas trainings
"My colleagues specifically looked for a sysadmin course for Docker with another provider and had an instructor who only set up an IDE for them and then only worked on a task sheet with development tasks. I had a course with lots of background information, an instructor who had a really extensive knowledge of the whole subject matter beyond the slides, and I feel optimally informed."
"From my perspective, the workshop had the right speed and an appropriate level of challenge. The subject matter was explained clearly by the instructor and practically consolidated with well-distributed exercises. Adjusting the workshop focus to the participants wishes was not a problem. Valuable practical experiences were shared, and even more specific questions were gladly answered. The instructor's professional expertise and extensive practical experience on the subject gave this workshop a special quality."
"The "Docker & Kubernetes Bundle" training provided me with solid, practical knowledge for everyday work and enabled me to handle Docker and Kubernetes professionally. The excellently structured material offers real added value, even beyond the workshop. The combination of technical depth and interactive delivery by the trainer rounded off the whole experience. An experience that continues to help me even after the training."
"I really enjoyed the Docker & Kubernetes workshop at DevNinjas. Nico explained the complex topics around containers and orchestration in a very understandable and practical way.
